Laszlo Nagy cff06bd779 axi_dmac: Use AXI3 for DMAC in Intel projects 
The buffers inside the interconnect are sized based on maximum burst sizes
the masters can produce.
For AXI4 the max burst size is 128 but for these projects for the
default burst size of 128 bytes the DMACs are creating only burst of 8 or
16 beats depending on the bus width (128bits and 64 bits respectively).

These burst sizes can fit in the AXI3 protocol where the max burst
length is 16. Therefore the interconnect will be reduced.

The observed reduction is around 4 Mb of block RAM per project.
Another benefit is a better timing closure,
since these buffers reside in the DDR3 clock domain.

HDL Reference Designs

Analog Devices Inc. HDL libraries and projects.

Getting started

This repository supports reference designs for different Analog Devices boards based on Intel and Xilinx FPGA development boards or standalone.

Prerequisites

or

Please make sure that you have the required tool version.

How to build a project

For building a projects, you have to use the GNU Make tool. If you're a Windows user please checkout this page, to see how you can install this tool.

To build a project, checkout the latest release, after that just cd to the project that you want to build and run make:

 [~]cd projects/fmcomms2/zc706
 [~]make

A more comprehensive build guide can be found under the following link: https://wiki.analog.com/resources/fpga/docs/build

Software

In general all the projects have no-OS (baremetal) and a Linux support. See no-OS or Linux for more information.

Which branch should I use?

  • If you want to use the most stable code base, always use the latest release branch.

  • If you want to use the greatest and latest, check out the master branch.
